Nixon presidential library hosts reunion for 200 Vietnam POWs 40 years after their release

Two hundred American former prisoners of war who were taken captive during the Vietnam War are arriving in Southern California to celebrate the 40th anniversary of their release.

The three-day gala starts Thursday at the Richard Nixon Presidential Library & Museum in Yorba Linda. It will include a military flyover, wreath-laying ceremony and tours of a special exhibit on the prisoners' return home.

The reunion runs through Saturday and marks the 40th anniversary of a special White House dinner hosted by President Nixon on May 23, 1973, to honor the 571 American captives.

Nixon resigned a year later in the face of impeachment over Watergate, but many of the former POWs regard him as a hero for securing their freedom.
